STARTING DEVICE FOR EXPLOSION-ENGINES.

Specification of Letters Patent. Patentd Oct, 25, 1920.

Application filed October 1, 1918. Serial No. 256,410.

To all whom it may concern:

Be it known that I, CHARLES LOUIS FRANoIs Moeuri, a citizen of theFrench Republic, residing at Le Havre, Seine, Inferieure, France, haveinvented certain new and useful Improvements in Starting. Devices forExplosion-Engines, of which the following is a full, clear, and exactspecification.

The invention has for its object the application of explosives forstarting explosion engines, and the device by which the said applicationmay be conveniently putinto practice.

A single apparatus or a number of apparatus equal to that of thecylinders may be used; the same may be actuated by the motor shaft bymeans of pinions or chains.

The said invention is illustrated by way of example in the accompanying.drawing, in which .Figure 1 shows the starting device, partly inelevation, partly in vertical section.

Fig. 2'is a plan of the same.

Fig. 3 is a front view of the olial.

Fig. 4 is an edge view of the same dial.

Fig. 5 is means for holding the. hammer in set position and permittingit to move to firing position.

The apparatus comprises a headbody 1 on which is screwed the movablehead 2 provided with a hand lever 3, the said moveable head being closedby a stopper 4 also screwed thereon; inside the headis the hammer 5 withits spiral spring 6. The hammerwill act upon a priming cap 7 at thecenter of a case or cartridge 8 which contains the powder load, the baseof the said cartridge has a groove 9 wherein engages a flange 10 actingas a cartridge-extractor and provided in the lower part of the movablehead.

-The device may be very easily put into position and released, owing tothe U-sha ed groove 9; the trigger or loosing mem er may be of any kind,such as, for instance a finger 12 which will engage a slit 13 controlledby a lever 14 carried by the hammer.

There is a starter for each cylinder and each of the said starters isconnected with the cylinder by means of a pipe.

a perspective detail showing the In operation the starter, which has toactuate the engine, is loaded by means of a cartridge, for this purposeand in order to ascertam upon what cylinder it is of advantage to act,there is provided near the startmg devices a dial 15 over or in front ofwhich will move a pointer 11 actuated I by the engine cam shaft androtating, for instance 1n the example of a four-strokecycle-engine, atthe half-speed of the latter.

It is very easy to ascertain the position of the pistons, as the dial isprovided with numbers which correspond to the number of cylinders andthe pointer will indicate the cylinder which has to receive the impulseof the explosive.

What I claim is:

1. In a starting device for explosive engmes, the combination of acasing formed wlth a cartridge receiving seat, a plug screwed into thecasing, an extractor on the plug to extract a cartridge from the casing,the plug having a central bore and an angular slot, a rod extendingthrough the bore I of the plug adapted to explode a cartridge held inthe seat, a flange on the rod, a sprmg between the flange and the topwall of the bore, a trigger extending from the rod and through theangular slot, whereby to hold the rod elevated and the spring undercompression, or to release the rod, and a handle on the rod to rotatesame to set or release the trigger;

2. In a starting device for explosive engines, the combination of acasing formed with a cartridge receiving seat, a plug screwed into thecasing, the plug having a central bore and an an lar slot, a rodextending through the ore, and provided with a trigger which engages inthe angular slot, a flange on the rod, aspring interposed between thetop wall of the bore and the flange, and a handle for raising androtating the rod to set it in the firing position.

Witness my signature this 30 day of I August, 1918.
